Will Smith celebrates his son, Jaden Smith, 20, birthday with throw back snaps

Jaden Smith celebrated his 20th birthday on Sunday.

But leave it to his movie star dad to remind him that he was once a cute little kid with a love for superheroes.

Will Smith shared a picture on his Instagram of Jaden wearing a Spiderman outfit and wrote: 'Happy Bday, Jaden. 20 Years Old ~ WHOA!  And Wait... I don’t know what the big deal was when you wore a White Batman Suit to Prom? You have ALWAYS worn superhero suits on your dates!'
